He should be cloned. In the cloning process the original Godzilla becomes super-intelligent and starts a high-tech crime-fighting organization that is devoted to battling the Godzilla-clone who looks just like Godzilla only has a mustache/goatee and is called Allizdog. Hilarity ensues of course.

After all this time, I actually prefer the "Earth Defender" version of Godzilla rather then the allegorical force of destruction personified version. I'd like to see him fight several monsters, with preferably minimal human presence in the movie. Unless the human presence is like how it was in Final Wars.

I say he should do all three: fight a tag-team of both a pre-existing Americanized Toho monster AND a new monster (preferably Winston's Gryphon - that puppy just looks bad@$$) AND have a sh**-fit and tear up New York.
